I'm curious about the Canadian manufacturer of M marked No36M grenades. I've always understood that M indicated grenades made by Montreal Munitions. However, a friend has suggested that this may not be the case. More than one source including histories of a company called Maxwells Ltd of St. Mary's, Ontario indicate that the company switched all of it's production during WW2 to the manufacture of grenades. If this is correct, could that mean that M actually indicates Maxwells and not Montreal Munitions? Or, could it be that Maxwells produced grenades for one of the other known manufacturers?
Something that I just recently noticed is that I have several M marked grenades but one has the M in a lower position on the body than all of the others I have seen. Simply a variant or something else?
